This mod creates **intelligent spawn zones** across your map that activate when players get close. Each zone can have multiple spawn points with different entity types, spawn chances, and behaviors. Perfect for:
– Military zones with elite zombies
– Underground bunkers with precise positioning
– Wildlife areas with predator packs
– Urban hordes in cities
– Boss encounters at POIs
– Dynamic events anywhere on the map
Basic Zone Setup
Underground Bunker
Global Settings
– systemEnabled (1/0): Master on/off switch
– checkInterval: How often to check for players (seconds)
– maxEntitiesPerZone: Performance limit per zone
– entityLifetime: Auto-cleanup time (0 = disabled)
– minSpawnDistanceFromPlayer: Safety distance
Zone Parameters
– name: Unique identifier for the zone
– enabled (1/0): Enable/disable this specific zone
– position: Center point of the zone "X Y Z"
– triggerRadius: How close players need to be to activate
– spawnChance: Probability of spawning (0.0-1.0)
– despawnOnExit (1/0): Remove entities when players leave
– despawnDistance: How far players must go to trigger cleanup
– respawnCooldown: Seconds before zone can activate again
Spawn Point Settings
– position: Exact spawn location "X Y Z"
– radius: Random spawn area around position
– tierIds: Which entity tiers can spawn here
– entities: Number of entities to spawn at this point
– useFixedHeight (1/0): Use exact Y coordinate (for bunkers)
Tier System
Create categories of entities by difficulty or type:
Use these in your server console for testing:
This system can spawn ANY living entity in DayZ:
– ✅ Vanilla Zombies (all ZmbM_*, ZmbF_* classes)
– ✅ Vanilla Animals (all Animal_* classes)
– ✅ Modded Creatures (mutants, custom zombies, etc.)
– ✅ Custom NPCs (player-like entities)
– ✅ Mod Compatibility (works with any creature mod)
If it’s alive and has a classname, this system can spawn it!
Performance Optimization
– Intelligent checking only when players nearby
– Automatic cleanup of dead entities
– Configurable update intervals
– Entity lifetime limits
Flexible Spawning
– Multiple spawn points per zone
– Mixed entity tiers per point
– Random positioning within radius
– Exact height control for buildings
Smart Behavior
– Spawn protection (won’t spawn on players)
– Cooldown prevention (no spam spawning)
– Exit-based despawning
– Chance-based encounters
Entities not spawning?
– Check zone enabled status
– Verify spawn chance settings
– Ensure players within trigger radius
– Use `QuickStatus()` for diagnostics
Performance issues?
– Increase `checkInterval` to 30+ seconds
– Reduce `maxEntitiesPerZone`
– Remove unused zones
– Lower entity counts per spawn point
Bunker spawning problems?
– Always use `"useFixedHeight": 1`
– Test coordinates in-game first
– Ensure Y-coordinate is above floor
